1110
1111 - Other events (that pass the server_id test) will decrease
1112 slave_skip_counter.
1113
1114 - Except in one case: if slave_skip_counter==1, it will only
1115 decrease to 0 if we are at a so-called group boundary. Here, a
1116 group is defined as the range of events that represent a single
1117 transaction in the relay log: see comment for is_in_group in
1118 rpl_rli.h for a definition.
1119
1120 The difficult part to implement is the logic to avoid decreasing
1121 the counter to 0. Given that groups have the form described in
1122 is_in_group in rpl_rli.h, we implement the logic as follows:
1123
1124 - Gtid, Rand, User_var, Int_var will never decrease the counter to
1125 0.
1126
1127 - BEGIN will set thd->variables.option_bits & OPTION_BEGIN and
1128 COMMIT/Xid will clear it. This happens regardless of whether
1129 the BEGIN/COMMIT/Xid is skipped itself.
1130
1131 - Other events will decrease the counter unless OPTION_BEGIN is
1132 set.

2636 The method maps the event to a Worker and return a pointer to it.
2637 Sending the event to the Worker is done by the caller.
2638
2639 Irrespective of the type of Group marking (DB partitioned or BGC) the
2640 following holds true:
2641
2642 - recognize the beginning of a group to allocate the group descriptor
2643 and queue it;
2644 - associate an event with a Worker (which also handles possible conflicts
2645 detection and waiting for their termination);
2646 - finalize the group assignment when the group closing event is met.
2647
2648 When parallelization mode is BGC-based the partitioning info in the event
2649 is simply ignored. Thereby association with a Worker does not require
2650 Assigned Partition Hash of the partitioned method.
2651 This method is not interested in all the taxonomy of the event group
2652 property, what we care about is the boundaries of the group.
2653
2654 As a part of the group, an event belongs to one of the following types:
2655
2656 B - beginning of a group of events (BEGIN query_log_event)
2657 g - mini-group representative event containing the partition info
2658 (any Table_map, a Query_log_event)
2659 p - a mini-group internal event that *p*receding its g-parent
2660 (int_, rand_, user_ var:s)
2661 r - a mini-group internal "regular" event that follows its g-parent
2662 (Delete, Update, Write -rows)
2663 T - terminator of the group (XID, COMMIT, ROLLBACK, auto-commit query)
2664
2665 Only the first g-event computes the assigned Worker which once
2666 is determined remains to be for the rest of the group.
2667 That is the g-event solely carries partitioning info.
2668 For B-event the assigned Worker is NULL to indicate Coordinator
2669 has not yet decided. The same applies to p-event.
2670
2671 Notice, these is a special group consisting of optionally multiple p-events
2672 terminating with a g-event.
2673 Such case is caused by old master binlog and a few corner-cases of
2674 the current master version (todo: to fix).
2675
2676 In case of the event accesses more than OVER_MAX_DBS the method
2677 has to ensure sure previously assigned groups to all other workers are
2678 done.
2679
2680
2681 @note The function updates GAQ queue directly, updates APH hash
2682 plus relocates some temporary tables from Coordinator's list into
2683 involved entries of APH through @c map_db_to_worker.
2684 There's few memory allocations commented where to be freed.
2685
2686 @return a pointer to the Worker struct or NULL.

3436 which master connection the temp table belongs.
3437 Now imagine we (write()) are called by the slave SQL thread (we are
3438 logging a query executed by this thread; the slave runs with
3439 --log-replica-updates). Then this query will be logged with
3440 thread_id=the_thread_id_of_the_SQL_thread. Imagine that 2 temp tables of
3441 the same name were created simultaneously on the master (in the masters
3442 binlog you have
3443 CREATE TEMPORARY TABLE t; (thread 1)
3444 CREATE TEMPORARY TABLE t; (thread 2)
3445 ...)
3446 then in the slave's binlog there will be
3447 CREATE TEMPORARY TABLE t; (thread_id_of_the_slave_SQL_thread)
3448 CREATE TEMPORARY TABLE t; (thread_id_of_the_slave_SQL_thread)
3449 which is bad (same thread id!).
3450
3451 To avoid this, we log the thread's thread id EXCEPT for the SQL
3452 slave thread for which we log the original (master's) thread id.
3453 Now this moves the bug: what happens if the thread id on the
3454 master was 10 and when the slave replicates the query, a
3455 connection number 10 is opened by a normal client on the slave,
3456 and updates a temp table of the same name? We get a problem
3457 again. To avoid this, in the handling of temp tables (sql_base.cc)
3458 we use thread_id AND server_id. TODO when this is merged into
3459 4.1: in 4.1, slave_proxy_id has been renamed to pseudo_thread_id
3460 and is a session variable: that's to make mysqlbinlog work with
3461 temp tables. We probably need to introduce
3462
3463 SET PSEUDO_SERVER_ID
3464 for mysqlbinlog in 4.1. mysqlbinlog would print:
3465 SET PSEUDO_SERVER_ID=
3466 SET PSEUDO_THREAD_ID=
3467 for each query using temp tables.

3498 of this x>=4 master segfault (expecting a zero when there is
3499 none). Remaining compatibility problems are: the older slave will not
3500 find the catalog; but it is will not crash, and it's not an issue
3501 that it does not find the catalog as catalogs were not used in these
3502 older MySQL versions (we store it in binlog and read it from relay log
3503 but do nothing useful with it). What is an issue is that the older slave
3504 will stop processing the Q_* blocks (and jumps to the db/query) as soon
3505 as it sees unknown Q_CATALOG_NZ_CODE; so it will not be able to read
3506 Q_AUTO_INCREMENT*, Q_CHARSET and so replication will fail silently in
3507 various ways. Documented that you should not mix alpha/beta versions if
3508 they are not exactly the same version, with example of 5.0.3->5.0.2 and
3509 5.0.4->5.0.3. If replication is from older to new, the new will

3911 We also force AUTOCOMMIT=1. Rationale (cf. BUG#29288): After
3912 fixing BUG#26395, we always write BEGIN and COMMIT around all
3913 transactions (even single statements in autocommit mode). This is
3914 so that replication from non-transactional to transactional table
3915 and error recovery from XA to non-XA table should work as
3916 expected. The BEGIN/COMMIT are added in log.cc. However, there is
3917 one exception: MyISAM bypasses log.cc and writes directly to the
3918 binlog. So if autocommit is off, master has MyISAM, and slave has
3919 a transactional engine, then the slave will just see one long
3920 never-ending transaction. The only way to bypass explicit
3921 BEGIN/COMMIT in the binlog is by using a non-transactional table.
3922 So setting AUTOCOMMIT=1 will make this work as expected.
3923
3924 Note: explicitly replicate AUTOCOMMIT=1 from master. We do not
3925 assume AUTOCOMMIT=1 on slave; the slave still reads the state of
3926 the autocommit flag as written by the master to the binlog. This
3927 behavior may change after WL#4162 has been implemented.

3950 In what follows, we define in which cache, trx-cache or stmt-cache,
3951 this Query Log Event will be written to.
3952
3953 If ignore_cmd_internals is defined, we rely on the is_trans flag to
3954 choose the cache and this is done in the base class Log_event. False
3955 means that the stmt-cache will be used and upon statement commit/rollback
3956 the cache will be flushed to disk. True means that the trx-cache will
3957 be used and upon transaction commit/rollback the cache will be flushed
3958 to disk.
3959
3960 If set immediate cache is defined, for convenience, we automatically
3961 use the stmt-cache. This mean that the statement will be written
3962 to the stmt-cache and immediately flushed to disk without waiting
3963 for a commit/rollback notification.
3964
3965 For example, the cluster/ndb captures a request to execute a DDL
3966 statement and synchronously propagate it to all available MySQL
3967 servers. Unfortunately, the current protocol assumes that the
3968 generated events are immediately written to diks and does not check
3969 for commit/rollback.
3970
3971 Upon dropping a connection, DDLs (i.e. DROP TEMPORARY TABLE) are
3972 generated and in this case the statements have the immediate flag
3973 set because there is no commit/rollback.
3974
3975 If the immediate flag is not set, the decision on the cache is based
3976 on the current statement and the flag is_trans, which indicates if
3977 a transactional engine was updated.
3978
3979 Statements are classified as row producers (i.e. can_generate_row_events())
3980 or non-row producers. Non-row producers, DDL in general, are treated
3981 as the immediate flag was set and for convenience are written to the
3982 stmt-cache and immediately flushed to disk.
3983
3984 Row producers are handled in general according to the is_trans flag.
3985 False means that the stmt-cache will be used and upon statement
3986 commit/rollback the cache will be flushed to disk. True means that the
3987 trx-cache will be used and upon transaction commit/rollback the cache
3988 will be flushed to disk.
3989
3990 Unfortunately, there are exceptions to this non-row and row producer
3991 rules:
3992
3993 . The SAVEPOINT, ROLLBACK TO SAVEPOINT, RELEASE SAVEPOINT does not
3994 have the flag is_trans set because there is no updated engine but
3995 must be written to the trx-cache.
3996
3997 . SET If auto-commit is on, it must not go through a cache.
3998
3999 . CREATE TABLE is classfied as non-row producer but CREATE TEMPORARY
4000 must be handled as row producer.
4001
4002 . DROP TABLE is classfied as non-row producer but DROP TEMPORARY
4003 must be handled as row producer.
4004
4005 Finally, some statements that does not have the flag is_trans set may
4006 be written to the trx-cache based on the following criteria:
4007
4008 . updated both a transactional and a non-transactional engine (i.e.
4009 stmt_has_updated_trans_table()).
4010
4011 . accessed both a transactional and a non-transactional engine and
4012 is classified as unsafe (i.e. is_mixed_stmt_unsafe()).
4013
4014 . is executed within a transaction and previously a transactional
4015 engine was updated and the flag binlog_direct_non_trans_update
4016 is set.

4318 relay logs (that is, there is no relay log with a format change
4319 except within the 3 first events, which mysqlbinlog handles
4320 gracefully). So this code should always be good.

5333 would make the header be "shifted" compared to other events.

8223 For each column in the given table checks if it is
8224 signaled in the bitmap. This is most useful when deciding
8225 whether a before image (BI) can be used or not for
8226 searching a row. If no column is signaled, then the
8227 image cannot be used for searching a record (regardless
8228 of using position(), index scan or table scan). Here is

8232 MASTER> CREATE TABLE t1 (a int, b int, c int, primary key(c));
8233 SLAVE> CREATE TABLE t1 (a int, b int);
8234 MASTER> INSERT INTO t1 VALUES (1,2,3);
8235 MASTER> UPDATE t1 SET a=2 WHERE b=2;
8236
8237 For the update statement only the PK (column c) is
8238 logged in the before image (BI). As such, given that
8239 the slave has no column c, it will not be able to
8240 find the row, because BI has no values for the columns
8241 the slave knows about (column a and b).
8242

9230 This handles the case that the BI was read successfully, but an
9231 error happened while looking up the row. In this case, the AI
9232 has not been read, so the read position is between the two
9233 images. In case the error is idempotent, we need to move the
9234 position to the end of the row, and therefore we skip past the
9235 AI.
9236
9237 The normal behavior is:
9238
9239 When unpack_row reads a row image, and there is no error,
9240 unpack_row sets m_curr_row_end to point to the end of the image,
9241 and leaves m_curr_row to point at the beginning.
9242
9243 The AI is read from Update_rows_log_event::do_exec_row. Before
9244 calling unpack_row, do_exec_row sets m_curr_row=m_curr_row_end,
9245 so that it actually reads the AI. And again, if there is no
9246 error, unpack_row sets m_curr_row_end to point to the end of the
9247 AI.
9248
9249 Thus, the positions are moved as follows:
9250
9251 +--------------+--------------+
9252 | BI | AI | NULL
9253 +--------------+--------------+
9254 0. Initial values ^m_curr_row ^m_curr_row_end
9255 1. Read BI, no error
9256 ^m_curr_row ^m_curr_row_end
9257 2. Lookup BI
9258 3. Set m_curr_row
9259 ^m_curr_row
9260 ^m_curr_row_end
9261 4. Read AI, no error
9262 ^m_curr_row ^m_curr_row_end
9263
9264 If an error happened while reading the BI (e.g. corruption),
9265 then we should not try to read the AI here. Therefore we do not
9266 read the AI if m_curr_row_end==NULL.
9267
9268 If an error happened while looking up BI, then we should try to
9269 read AI here. Then we know m_curr_row_end points to beginning of
9270 AI, so we come here, set m_curr_row=m_curr_row_end, and read the
9271 AI.
9272
9273 If an error happened while reading the AI, then we should not
9274 try to read the AI again. Therefore we do not read the AI if
9275 m_curr_row==curr_bi_start.

10029 This behaviour is necessary due to an inconsistency, between storage
10030 engines, regarding the 'm_cols' bitset and generated columns: while
10031 non-NDB engines always include the generated columns for write-rows
10032 events, NDB doesn't if not necessary. The previous execution order
10033 would set all generated columns bits to '1' in 'write_set', since
10034 'mark_generated_columns()' is expecting that every column is present
10035 in the log event. This would break replication of generated columns
10036 for NDB.
10037
10038 For engines that include every column in write-rows events, this order
10039 makes no difference, assuming that the master uses the same engine,
10040 since the master will include all the bits in the image.
10041
10042 For use-cases that use different storage engines, specifically NDB
10043 and some other, this order may break replication due to the
10044 differences in behaviour regarding generated columns bits, in
10045 wrote-rows event bitsets. This issue should be further addressed by
10046 storage engines handlers, by converging behaviour regarding such use
10047 cases.

10553 @ingroup Replication
10554
10555 @page PAGE_RPL_FIELD_METADATA How replication of field metadata works.
10556
10557 When a table map is created, the master first calls
10558 Table_map_log_event::save_field_metadata() which calculates how many
10559 values will be in the field metadata. Only those fields that require the
10560 extra data are added. The method also loops through all of the fields in
10561 the table calling the method Field::save_field_metadata() which returns the
10562 values for the field that will be saved in the metadata and replicated to
10563 the slave. Once all fields have been processed, the table map is written to
10564 the binlog adding the size of the field metadata and the field metadata to
10565 the end of the body of the table map.
10566
10567 When a table map is read on the slave, the field metadata is read from the
10568 table map and passed to the table_def class constructor which saves the
10569 field metadata from the table map into an array based on the type of the
10570 field. Field metadata values not present (those fields that do not use extra
10571 data) in the table map are initialized as zero (0). The array size is the
10572 same as the columns for the table on the slave.
10573
10574 Additionally, values saved for field metadata on the master are saved as a
10575 string of bytes (uchar) in the binlog. A field may require 1 or more bytes
10576 to store the information. In cases where values require multiple bytes
10577 (e.g. values > 255), the endian-safe methods are used to properly encode
10578 the values on the master and decode them on the slave. When the field
10579 metadata values are captured on the slave, they are stored in an array of
10580 type uint. This allows the least number of casts to prevent casting bugs
10581 when the field metadata is used in comparisons of field attributes. When
10582 the field metadata is used for calculating addresses in pointer math, the
10583 type used is uint32.
10584 */
10585
10586 #if defined(MYSQL_SERVER)
10587 /**
10588 Save the field metadata based on the real_type of the field.
10589 The metadata saved depends on the type of the field. Some fields
10590 store a single byte for pack_length() while others store two bytes
10591 for field_length (max length).
10592
10593 @retval 0 Ok.
10594
10595 @todo
10596 We may want to consider changing the encoding of the information.
10597 Currently, the code attempts to minimize the number of bytes written to
10598 the tablemap. There are at least two other alternatives; 1) using
10599 net_store_length() to store the data allowing it to choose the number of
10600 bytes that are appropriate thereby making the code much easier to
10601 maintain (only 1 place to change the encoding), or 2) use a fixed number
10602 of bytes for each field. The problem with option 1 is that net_store_length()
10603 will use one byte if the value < 251, but 3 bytes if it is > 250. Thus,
10604 for fields like CHAR which can be no larger than 255 characters, the method
10605 will use 3 bytes when the value is > 250. Further, every value that is
10606 encoded using 2 parts (e.g., pack_length, field_length) will be numerically
10607 > 250 therefore will use 3 bytes for eah value. The problem with option 2
10608 is less wasteful for space but does waste 1 byte for every field that does
10609 not encode 2 parts.

10823
10824 It checks that there hasn't been any corruption by verifying that there
10825 are no duplicate entries with different properties.
10826
10827 In some cases, some binary logs could get corrupted, showing several
10828 tables mapped to the same table_id, 0 (see: BUG#56226). Thus we do this
10829 early sanity check for such cases and avoid that the server crashes
10830 later.

10832 In some corner cases, the master logs duplicate table map events, i.e.,
10833 same id, same database name, same table name (see: BUG#37137). This is
10834 different from the above as it's the same table that is mapped again
10835 to the same identifier. Thus we cannot just check for same ids and
10836 assume that the event is corrupted we need to check every property.
10837

12314 possible, we can replace it with an UPDATE, but that will not
12315 work on InnoDB if FOREIGN KEY checks are necessary.
12316
12317 I (Matz) am not sure of the reason for the last_uniq_key()
12318 check as, but I'm guessing that it's something along the
12319 following lines.
12320
12321 Suppose that we got the duplicate key to be a key that is not
12322 the last unique key for the table and we perform an update:
12323 then there might be another key for which the unique check will
12324 fail, so we're better off just deleting the row and inserting
12325 the correct row.
